Dead-time generating circuit

摘要

A dead-time generating circuit includes a first gate for generating a gate signal corresponding to a predetermined cutting width, and a second gate for cutting an input signal to be cut by the gate signal by the predetermined cutting width determined by a user and outputting the result. Therefore, an arbitrary block of a pulse width modulated (PWM) signal (whatever it may be in a logic "high" or "low") applied to the inverter of an AC servo driving circuit can be cut constantly by a predetermined cutting width. Also, the cutting width can be adjusted easily by the user.
